Method for wet mud material drying and liquid molten material cold quenching

Abstract

The invention discloses a method for wet mud material drying and liquid molten material cold quenching. The method comprises the following steps: supplying fluidized gas from the bottom of a fluidizedbed by using cured cold-quenched particles with fine particle sizes as bed materials, and supplying a liquid molten material and a wet mud material into the fluidized bed for contact so as to finishcold quenching of the liquid molten material and drying of the wet mud material. Therefore, the provided method complementarily combines two requirements of drying of the wet mud material and cold quenching of the liquid molten material, drying of the wet mud material and cold quenching of the liquid molten material in one piece of equipment can be achieved at the same time, so that the waste heatof the liquid molten material is fully recycled, the problem that heat of existing high-temperature liquid molten materials cannot be fully utilized is solved, and the problem that fuel consumption is increased due to the fact that existing mud materials are dried through the fluidized bed is solved.

Description

technical field [0001] The invention belongs to the field of thermal energy engineering, and in particular relates to a method for drying a quenched liquid molten material with wet mud. Background technique [0002] A variety of processes will discharge high-temperature liquid molten material. At present, the commonly used cooling method is water quenching, that is, the liquid molten material falls into water and is quenched into small particles during rapid cooling. This sharp cooling keeps it in a glassy state with good reactivity of its components. The disadvantage of this method is that the residual heat carried by the liquid molten material is completely lost. For this reason, technologies such as gas quenching, rotary granulation, and fluidized bed heat exchange with cooling and heating surfaces have been developed to achieve both cooling and heat recovery. However, due to complex equipment, poor cooling effect and heat recovery rate low and rarely used. People are ...
